[petsc-dev] VecCreateGhost on GPUs

Hi all,

I've come across a problem with using ghosted vectors on GPUs, using CUDA backend. This is with the latest PETSc release version (3.18.5).

I saw that there is already an issue on Gitlab regarding this issue (https://gitlab.com/petsc/petsc/-/issues/1096), and also an associated branch and merge request (https://gitlab.com/petsc/petsc/-/merge_requests/4542), but there doesn't seem to have been any activity on the merge request for about a year.

Are there any plans to get this fix for VecCreateGhost on GPUs into the main PETSc branch?
